I would move this into the `robot.respond` block, and make it do `msg.send`. For users of the system, the command would just fail, and it'd take some digging into the logs to find the output for this little `console.log`.

It might make sense to add a helper to twitterConfig that takes a `msg` object so it can output what goes wrong. Like:

```coffeescript
auth = twitterConfig.defaultCredentials()
unless auth.checkEnvironment(msg)
   return
```

Then have checkEnvironment do the `msg.send` for errors, and return false if something isn't set.
